Yuken A3H180 Series High-Pressure Axial Piston Variable Pump

Product Overview: The Yuken A3H series is a high-pressure, high-flow axial piston variable pump engineered for Open Circuit industrial hydraulic systems. As an enhanced evolution of the classic A series, the A3H180 is built to withstand extreme continuous operating pressures, making it a staple in large forging presses, injection molding machines, steel mill equipment, and heavy-duty power units. Core models such as A3H180-FR09-55A4K-10 feature advanced Constant Power Control (FR09) logic, ensuring stable power output and protecting the prime mover from overload during intensive load fluctuations.

Key Technical Advantages:

• Extreme Pressure Capability: The A3H series is specifically reinforced for high-pressure cycles. It boasts a rated operating pressure of 28 MPa (280 Bar) with peaks reaching 35 MPa. Reinforced piston groups guarantee structural integrity during high-displacement output.

• Intelligent Constant Power Control (FR09): Equipped with the advanced FR09 controller. Models like the A3H180-FR09-45A4K-10 automatically modulate flow based on load pressure, keeping input power within a preset range for maximized energy efficiency and reduced motor strain.

• Excellent Self-Priming & Low Noise: Optimized internal flow paths provide exceptional suction characteristics, effectively preventing cavitation even at high speeds. The acoustically reinforced housing meets modern industrial standards for workplace noise reduction.

• 100% Industrial Reliability: Adhering to the Series 10 design specifications. Whether in the 55A4K or 45A4K configuration, the mounting flanges, shaft splines, and port layouts are fully compliant with standard specs, ensuring a seamless “plug-and-play” replacement.
